3.HARDWARE SETUP

26)System Management Interrupt Switch Lead (2-pin SMI)

This allows the user to manually place the system into a suspend mode or “Green” mode, where system activity is decreased to save electricity and expand the life of certain components when the system is not in use. This 2-pin connector con- nects to the case-mounted suspend switch. If you do not have a switch for the connector, you may use the “Turbo Switch.” SMI is activated when it detects a short to open moment and therefore leaving it shorted will not cause any prob- lems. This may require one or two presses depending on the position of the switch. Wake-up can be controlled by settings in the BIOS but the keyboard will always allow wake-up (the SMI lead cannot wake up the system).

27)System Message LED Lead (2-pin LED)

This indicates whether a message has been received from a fax/modem. The LED will remain lit when there is no signal and blink when there is data transfer or waiting in the inbox. This function requires ACPI OS and driver support.

28)ATX Power Supply Connector (20-pin block ATXPWR)

This connector connects to an ATX power supply. The plug from the power sup- ply will only insert in one orientation because of the different hole sizes. Find the proper orientation and push down firmly making sure that the pins are aligned.

IMPORTANT: Make sure that your ATX power supply can supply at least 10mA on the +5-volt standby lead (+5VSB). You may experience difficulty in powering ON your system if your power supply cannot support the load. For Wake- On-LAN support, your ATX power supply must supply at least 720mA +5VSB.
